3. Your patient asked you why dental images are important. Which of the following is th
io io io io io io io io io io io io io io


ecorrect response?
io io


a. An oral examination with dental images limits the practitioner to what is seen
io io io io io io io io io io io io io


clinically.
b. All dental diseases and conditions produce clinical signs and symptoms.
io io io io io io io io io

, c. Dental images are not a necessary component of comprehensive patient care.
io io io io io io io io io io


d. Many dental diseases are typically discovered only through the use of dental
io io io io io io io io io io io io


images.
ANSWER: D io


An oral examination without dental images limits the practitioner to what is seen clinically. Ma

4. The x-ray was discovered by
io io io io


a. Heinrich Geissler io


b. Wilhelm Roentgen io


c. Johann Hittorf io


d. William Crookes io




ANSWER: B io


Heinrich Geissler built the first vacuum tube in 1838. Wilhelm Roentgen discovered the
io io io io io io io io i o io io io


x-
ray on November 8, 1895. Johann Hittorf observed in 1870 that discharges emitted from the
io io io io io io io io io io io io io io io


negative electrode of a vacuum tube traveled in straight lines, produced heat, and resultedin
io io io io io io io io io io io io io io io


a greenish fluorescence. William Crookes discovered in the late 1870s that cathode rays wer
io io io io io io io io io io io io io


e streams of charged particles.

io io io io io io io io io io io io io


a. Otto Walkoff io


b. Wilhelm Roentgen io


c. Edmund Kells io


d. Weston Price io




ANSWER: C i o


Otto Walkoff was a German dentist who made the first dental radiograph. Wilhelm Roentgen
io io io io io io io io io io io io io io


was a Bavarian physicist who discovered the x-
io io io io io io io


ray. Edmund Kells exposed the first dental radiograph in the United States using a live person
io io io io io io io io io io io io io io io


. Price introduced the bisecting technique in 1904.

7. Who modified the paralleling technique with the introduction of the long-cone technique?
io io io io io io io io io io io


a. C. Edmund Kells io io


b. Franklin W. McCormack io io


c. F. Gordon Fitzgerald io io


d. Howard Riley Raper io io




ANSWER: C io

chnique with the introduction of the long-
io io io io io io


cone technique. This is the technique currently used. Howard Riley Raper modified the bise
io io io io io io io io io io io io io


cting technique and introduced the bite-wing technique in 1925.

8. Which of the following is an advantage of digital imaging?
io io io io io io io io io


a. Increased patient radiation exposure io io io


b. Increased patient comfort io io


c. Increased speed for viewing images io io io io


d. Increased chemical usage io io




ANSWER: C io


Patient exposure is reduced with digital imaging. Digital sensors are more sensitive to x-
io io io io io io io io io io io io io


rays than film. Digital sensors are rigid and bulky, causing decreased patient comfort. The im
io io io io io io io io io io io io io io


age from digital sensors is uploaded directly to the computer and monitor without the need for
io io io io io io io io io io io io io io io


chemical processing. This allows for immediate interpretation and evaluation. The image fro
